Answer:
75
Step-by-step explanation:
assuming that all are children(answer will be adult ticket at the end)
124×5.20=644.8
872.5-644.8=227.7
8.50-5.20=3.30
227.7÷3=75.9=7 5 tickets(no decimal cause tickets are sold as a whole)
So from that i think the formula would be
so then you find "x" by multiplying 470 x 28 which equals 13,160. Then you divide 13,160 by 40 which equals 329.
X=329
